UPDATE.
We took Jack into our normal vet. He diagnosed one of 2 things. Either Jack had a spontaneous hernated disk, or his spin had a "mini seizure". Any way you looked at it, Jack needed a specialist. Dr. A called the specialist and they were able to see us. After waiting 4 hours (the last hour with pudd'n in tow) we finally saw the specialist. He also said that Jack could have a disorder known as "MG" (I'm not going to spell it out). There is a thick lining around his esopogus, the past vomiting and the current drool coming (in rivers) out of his mouth could also be a possibility. It affects the nerves and could cause the paralysis in his back end. Jack is still at the specialist, they are running tests to figure out what it is. We will know more tomorrow. Right now I have an appointment with a 6 pack and bottle of wine. I don't want to be late, so I think I'll have a few right now. I'm going to NEED tomorrow night's drag show. Thank Goddess Venus is driving my sorry ass.
